c#3.0

using System;
using System.Collections;
namespace Iterator_test
{
 class Day
 {
    int days_idx = -1;
    private String[] days = { "mon", "tue", "wed","thu","fri","sat","sun" };
    public IEnumerable getdays()
    {
        days_idx++;
        yield return days[days_idx];
    }
 }
 class Program
 {
    static void Main(string[] args)
    {
        Day d = new Day();
        foreach (string day in d.getdays())
        {
            Console.WriteLine(day);
        }
    }
  }
}

Actually the output should be,

mon
tue
wed
thu
fri
sat 
sun

but its printing only "mon" as,

mon

What will be the reason?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
